Specification of Letters Patent.

Patented Sept. 15, 1908.

Application led September 9, 1907. Serial No. 391,861.

To all whom t may concern:

Be it known that l, SAMUEL G. GILLE- LAND, a citizen of the United States, residing at Spring Garden, in the county of Miller and State of Missouri, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification.

This invention relates to baling presses, and my obj ect is to produce a machine of this character which will perform its function efficiently and reliably and can be operated by engine or horse power.

A further object is to produce a baling press of simple, strong, durable 'and cheap construction.

fith these objects in view andothers as hereinafter appear the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which- F igure l, is a top plan view of a baling press embodying my invention. FiO. 2, is a side view of the same. Fig. 3, is a pfan view of the power end of the press with the sweep and turn-table omitted and with the press below the turn-table partly in section. Fig. 4, is a section taken on the line lVIV of Fig. 3. Fig. 5, is an enlarged section taken on the line V`V of Fig. 3. Fig. 6, is a sec tion taken on the line Vl-Vl of Fig. 3 on the same scale as Fig. 5. Fig. 7, is a horizontal section taken on the line VII-V11 of Fig. 2 buton a larger scale. Fig. 8, is a section taken on the line VlllVlIl of F ig'. 2 and on the same scale as Fig. 7. Fig. 9, is a detail perspective view of one of a pair of brackets hereinafter described and also shows in dotted lines one of the posts of the press frame. Fig. 10, is a detail perspective view of one of a pair of similar levers forming part of the invention.

ln the said drawings, l indicates the baling case provided with the usual feed opening 2, and hopper 3, communicating therewith. At the front end of the baling case is a pair of uprights 4 in which are j ournaled a horizontal transverse shaft 5 equipped centrally with a large peripherally grooved wheel 6, having lugs 7 projecting outward from its periphery at opposite sides of the groove and connected by a bolt 8.

9 indicates a plunger for reciprocating past the opening 2 in the baling case, and pivoted to said plunger at its rear end is a pitman 10,

`the inner side of the Las follows: 12 indicates a skeleton rectangular frame to rest on the ground and 13 is a longitudinal bar connecting the opposite sides of the skeleton frame. 14 is a longitudinal bar bolted upon bar 13 and provided centrally with an arched portion 15 as a central support for a turn-table 16, journaled upon a stationary vertical shaft 17 extending upward from bar 13, through the arch 15 of bar 14, a nut 18 securing the turn-table in place. This turn-table may form the head of a sweep 18a of any suitable type (see Fig. 2) or it may be in the form of a gear wheel as indicated in Figs. 1 and 4, 19 indicating the teeth of said wheel adapted for engagement with a gear pinion, not shown, driven by any suitable power. The turn table is provided with an outwardly projecting annular flange 20 engaged at its upper and lower sides by anti-.friction rollers 21 and 22 respectively carried by brackets 23 secured to the rectangular frame, these rollers tending to maintain the turn-table in a horizontal position and eliminate friction.

Secured to and depending from the turntable is a peripherally grooved elliptic cam 24, which cam stands in the position shown in Fig 3 when the pitman occupies substantially the position shown in Fig. 2, and proj ecting outward from said cam at diametrically opposite points are hooks 25 5 said hooks being preferably secured in sockets 26 in the cam by means of bolts 27 and in this connec` tion it should be stated that when the machine is operated by an engine, one of the hooks will be removed, whereas when it is operated by horse power both hooks will be employed.

A pair of bell crank levers are pivoted in the cam concentrically of the front or concave faces of the hooks with their outer arms 28 occupying and adapted to play in the outer arms of the V-shaped recesses 29, and with their inner arms 30 occupying and adapted to play in the inner arms of said V- shaped recesses, it being noted in this connection that said inner arms project beyond cam and are equipped with downturned ends 31 for engagement once in each revolution of the turn-table with a stud 32 projecting upwardly from plate 14,'the upper end of said stud being below the elliptic cam so that the latter may revolve above it.

33 indicates a substantially semicircular guide arranged concentrically of shaft 17 at one side of the longitudinal center of the machine of such size that the ends of the elliptic cam shall almost come in contact with its inner side in their turning movement.

uide is provided in its inner side with a horizontal slot 34 in the horizontal plane of hooks 25 and levers 30 and said slot is provided at its rear end with a flaring mouth 35 in order to properly receive and guide the hooks into the slots 34 in the revolution of the former, it being understood that at no time is more than one hook in engagement with the guide. The slot 34 opens into a vertical channel 36 which widens at the rear end of the guide as at 37 and at the front end of the guide as at 38, and from widened portion 37 of such channel to the other end it is deepened so as to provide the forwardly disposed shoulders 39 as an abutment for the upward projecting arms 41 of a link 40 fitting in the channel and connected at its rear end to a cable 42 which extends rearwardly and engages the peripherally-grooved wheel 6 and is attached at its rear end to the bolt 8 of said wheel. To prevent the cable from sagging and thus becoming disengaged from the groove of said wheel, 1 provide the underlying grooved sheave 43 carried by a bracket 44 secured to the baling case and to hold the cable in proper relation to the guide 33 1 employ a horizontally-arranged guide sheave 45 suitably journaled on frame 12, said sheave being equipped with a guard 46, through which the cable extends, it being noticed that when the plunger is withdrawn the cable and link extend in a straight line from sheave 45 with. the arms 41 of the link 40 inv engagement with shoulders 39 see Fig. 5, so that when a hook of the elliptic cam enters the slot 34 it will enter the link and come into engagement with its front end and thus draw the link around in the channel 36, this action resulting, through the cable connection, in revolving wheel 6 in the direction indicated by the arrow, Fig. 2 and causing the plunger to make its compression stroke, it being noted in this connection that this movement of said wheel is resisted by spring 47 secured at one end to plunger and at the other to the baling case, the chief function of said spring being to effect the recoil of the plunger at the proper time.

When the full stroke of the plunger has been made, the link has attained the position shown in dotted lines Fig. 3, that is, has entered the widened portion 38 of the channel 36 and as soon as it attains this position the arm 30 of the contiguous lever carried by the cam comes into engagement with the pin The 32 and is swung outwardly thereby, this out-I ward movement causing arm 28 of said lever to force the front end of the link outward until it is disengaged from the hook when the recoil of the plunger takes place and through the medium of the cable returns the link to its original position as shown in full lines Fig. 3.

1n practice the baling case will be charged with the material to be baled as soon as the recoil of the plunger takes place and in order to give time for such action the turn-table is adapted to revolve some distance before the second hook enters the guide and comes into engagement with the link to repeat the operation above described. When the press is operated by means of an engine one of the hooks 25 will be removed because the turntable would be revolved at such a rate of speed that the attendant would not have time to charge the baling case properly between the strokes of the plunger.

1t will be understood of course that the baling case and power portions of the machine must be securely anchored preliminary to the baling operation described. My preferred method of bracing them apart is through the medium of a knockdown framework constructed as followsz-48 is a bar 'fitted at its front end against the frame 12 and provided at its rear end with a socket plate 49.' 50 indicates a pair of forwardly diverging braces bolted as at 51 to bar 48 and as at 52 to frame 12, the front ends of said braces and the rear ends of the side bars of the frame beingl preferably step-jointed together as at 53, and to relieve the bolts 52 of bending strain the rear cross bar of frame 12 is provided with notches 54 to receive the front ends of the braces 50. 55 are braces provided with recesses 55 in their front ends to engage the rear corners of bar 48, the socket plate 49 holding said bars in the relations described. The bars 55 preferably slope upward and outward to abut against the posts 5 of the baling case and are held in such position by fitting in the brackets 57 secured to and projecting forwardly from said posts. Vhen the machine is in operation the press and power mechanisms are prevented from moving toward each other by the brace frame described. When the baling operation is over, the bracing frame can be easily and quickly removed from position so that the power mechanism and the baling case can be separately transported. 1t will be understood of course that the team which operates the press will travel around the power mechanism in the usual manner and once in each revolution step over the bracing framework and the cable, which being very close to the ground will be easily avoided.

1n each operation of the elliptic cam, it will be noticed that the hook picking up the exceeding the external link draws the same forward in the guide as explained so that the preliminary part of the compression stroke ofthe plunger shall be rapid for the purpose of bunching the loose hay in the baling case. By the time such hay begins to offer material resistance the cable is engaging the groove of the cam and moves inwardly toward the axis of the latter until the plunger has about completed its stroke, it being apparent by reference to Fig. 3 that because the cable thus gradually moves inward its speed of movement gradually diminishes and its power is proportionately increased, it being of course obvious that the link because traveling in guide 33 and in engagement with the hook 2, moves at uniform speed from the rear to the front end of the guide.

Frein the above description it will be apparent that I have produced a baling press possessing the features of advantage enumerated as desirable and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described as obvious modifications will suggest themselves to one skilled in the art.
